Answer:
You played 4 games
Step-by-step explanation:
You start with $18 and subtract 6 from the entry fee. Then, you divide the 12 you got from that and divide it by 3
Final answer:
To determine the number of games played, subtract the access fee from the total cost and then divide by the per-game price. In this case, the student paid for an access fee of $6, and played 4 games at $3 each to reach a total cost of $18.
Explanation:
The question posed is a basic algebra problem involving a fixed entry fee and a variable cost per game. The given information states that the access fee is $6 and the per-unit price, which in this case is the cost per game, is $3. If the total amount paid was $18, the number of games played can be calculated.
To solve, let's denote the number of games played as x. The total cost is made up of a fixed access fee plus the cost of the games played. The expression for the total cost is thus $6 (access fee) + $3x (cost of games).
The equation based on the total amount paid would be:
6 + 3x = 18
To find the value of x, we subtract the access fee from the total amount paid:
18 - 6 = 3x
That simplifies to:
12 = 3x
Which can then be solved by dividing both sides by 3:
x = 12 / 3
x = 4
The student thus played 4 games.

A botanist is working with a sample of algae cells in a petri dish. The change in the population of algae cells can be modeled by this function, where I represents the time in minutes
f(t) = 0.89€
Which statement describes the population of algae cells in the sample?
The population is decaying at a rate of 89% per minute,
The population is decaying at a rate of 11% per minute.
The population is growing at a rate of 89% per minute.
The population is growing at a rate of 11% per minute.
Answer:
The population is decaying at a rate of 11% per minute.
Step-by-step explanation:
We have that € is the inicial sample of algae cells, and f(t) shows the sample after t minutes.
As € is multiplied by a number between 0 and 1, that means the sample will decrease it's size as the time passes.
The inicial sample is €, and after 1 minute the sample will be 0.89€, that is, it will decrease by 0.11€ or 11% of the previous sample.
So the correct option is:
The population is decaying at a rate of 11% per minute.
Answer:
The correct answer is b) The population is decaying at a rate of 11% per minute.
Step-by-step explanation:
Given the function
f(t) = 0.89€
We can see that every time the variable v grows 1, the population grows only 0.89. So the population is decreasing. And the percentage of decreasing we get it by discounting 1 -0.89= 11%

What would be the coordinates at 315° if the coordinates at 135° are at (-square root 2/2, square root 2/2)?
Answer:
We choose C
Step-by-step explanation:
the coordinates at 135° are at ([tex]\frac{-\sqrt{2} }{2}[/tex], [tex]\frac{\sqrt{2} }{2}[/tex] )
As we can see, the x coordinate of the point is negative and the y coordinate of it is positive.
So this point is located at the quadrant ii
From 135 ° to 315°, it is rotated 180°
=> Each coordinate (x,y) is changed to (-x,-y)
= ([tex]\frac{\sqrt{2} }{2}[/tex], [tex]-\frac{\sqrt{2} }{2}[/tex] ) the new coordinate is located in quadrant iii
We choose C

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between (height) and (arm span) is shown in the scatterplot below. The equation of the line of best fit modeling this relationship is given:
y=4.5+0.977x
Mike is 172 cm tall and George is 165 cm tall. Using the model, how many centimeters longer would we expect Mike's arm span to be than George's? Round your answer to the thousandths place.
Answer: Mike's arm span is 7.165 cm longer than the George's one.
Step-by-step explanation:
We have that the association between height and arm span is modeled by the equation
y = 4.5 + 0.977*x
where y is height and x is arm span.
Mike is 172 cm tall, so his arm span is:
172cm = 4.5 + 0.977*x
x = (172 - 4.5)/0.977 = 171.443 cm
and George is 165 cm tall, so his arm span is:
x = (165 - 4.5)/0.977 = 164.278 cm
Then the difference between their arm span is:
171.443cm - 164.278cm = 7.165 cm
So Mike's arm span is 7.165 cm longer than the George's one.
lena's coffee shop makes a blend that us a mixture of two types of coffee. Type A coffee costs Lena $5.70 per pound, and type B coffee costs $4.25 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $885.30. how many pounds of type A coffee were used?
Answer: 39 pounds of type A coffee were used.
Step-by-step explanation:
Let x represent the number of pounds of type A coffee that were used in the blend.
Let y represent the number of pounds of type B coffee that were used in the blend.
Type A coffee costs Lena $5.70 per pound, and type B coffee costs $4.25 per pound. The total cost of the mixture is $885.30. It means that
5.7x + 4.25y = 885.3- - - - - - - - - -1
This month's blend used four times as many pounds of type B coffee as type A. It means that
y = 4x
Substituting y = 4x into equation 1, it becomes
5.7x + 4.25 × 4x = 885.3
5.7x + 17x = 885.3
22.7x = 885.3
x = 885.3/22.7
x = 39
y = 4x = 4 × 39
y = 156
The weight of Type A coffee used was approximately 39 pounds. This is determined by setting up and solving an equation based on the provided costs per pound of the coffees and the total cost.
Explanation:In this problem, we need to solve for the amount of Type A coffee. Let's represent the weight of Type A coffee as x and the weight of Type B coffee as 4x, as it's mentioned the weight of Type B is four times Type A. We know that the combination of Type A and B coffee costs $885.30, so we can set up the equation using the costs per pound for each type: (5.70*x) + (4.25*4x) = 885.30.
Solving this equation, we have 5.70x + 17x = 885.30, or 22.7x = 885.3. Dividing both sides by 22.7, we get x = 38.97 pounds. So, approximately 39 pounds of Type A coffee were used.

Talulah is an ecologist who studies the change in the penguin population of Antarctica over time. She observed that the population decays by a factor of 8/9 every 4 months. The population of penguins can be modeled by a function, P, which depends on the amount of time, t (in months). When Talulah began the study, she observed that there were 27,000 penguins in Antarctica. Write a function that models the population of the penguins t months since the beginning of Talulah's study. P(t) =
Answer:
P(t) = 27000 * (8/9)^(t/4)
Step-by-step explanation:
The population of penguins in Antarctica decays by 8/9 every 4 months, starting from an initial count of 27,000. The function for the penguin population P(t) after t months is P(t) = 27,000 × (8/9)^(t/4).
Explanation:Talulah, an ecologist, has observed that the population of penguins in Antarctica decays by a factor of 8/9 every 4 months. To model this decay, we can use an exponential decay function. Given that the initial population (P0) is 27,000 penguins, the function P(t) that models the population at time t (in months) since the beginning of Talulah's study is:
P(t) = P0 × (decay factor)(t/rate period)
Where P0 is the initial population, the decay factor is 8/9, and the rate period is 4 months. Plugging in these values gives us:
P(t) = 27,000 × (8/9)(t/4)
This function allows researchers to predict the penguin population at any given time t months after Talulah's initial observation.

First write an equation to represent the situation.
x=Maggie's age
x+(3x-3)=33
Then solve for x
x+3x-3=33
4x-3=33
4x-3+3=33+3
4x=36
4x/4=36/4
x=9
Then solve for Wendell's age
y=Wendell's age
y=3x-3
y=3(9)-3
y=27-3
y=24
Wendell is 24 years old.
By setting up and solving a system of equations based on the information given, we find that Wendell is 24 years old.
Explanation:In this question, we are asked to find out Wendell's age. First, we assume that Maggie's age is x. According to the problem, the sum of Wendell and Maggie's ages is 33, so we can write the first equation as Wendell's age + Maggie's age = 33. Next, we know that Wendell's age is three less than three times Maggie's age, so Wendell's age = 3*x - 3. Now, if we insert Wendell's age expression from the second equation into the first equation, we get 3*x - 3 + x = 33. When we solve this equation, we found that x equals to 9, hence, Maggie is 9 years old. That means, Wendell is 33 - 9 = 24 years old.

A truangular bandana has an area of 42 square inches. The height of the triangle is 5 1/4 inches. Enter and solve an equation ti find the length of the base of the triangle.
Answer: The length of the base of the triangle is 16 inches.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula
Area of a triangle (A) = base x height x 1/2
Replacing with the values given:
42 = b (5 1/4) 1/2
Solving for b (lenght of the base)
42 / (5 1/4) 1/2 = b
16 in = b
The length of the base of the triangle is 16 inches.
Feel free to ask for more if needed or if you did not understand something.
Final answer:
The length of the base of the triangle is 16 inches, calculated by using the area formula for a triangle and the given height.
Explanation:
To find the length of the base of the triangle, we use the formula for the area of a triangle, A = (b * h) / 2, where A is the area, b is the base, and h is the height. We know the area (A) is 42 square inches and the height (h) is 5 1/4 inches. Plugging these values into the formula gives us:
42 = (b*5.25) / 2
Multiplying both sides by 2 to isolate the term with b gives us:
84 = b* 5.25
Dividing both sides by 5.25 yields:
b = 84 / 5.25
Calculating this division, we get the length of the base (b):
b = 16 inches
